Abstract

BACKGROUND:A hypocholesterolemic effect of β-cyclodextrin (βCD) has been recently reported in various animals. This study was performed to determine the effect of dietary βCD on hypocholesterolemic effect, and its relationship to bile acid changes of 120 finishing pigs fed a commercial diet containing 0%, 5%, 7%, or 10% βCD for 30 days before slaughter.

RESULTS:Plasma total lipids, triacylglyceride, and total cholesterol of βCD supplemented pigs were lower (P < 0.05) than the control pigs. When 5%, 7%, or 10% βCD was supplemented to pigs, cholesterol levels of the plasma were reduced by 26.0%, 28.2%, and 31.3%, respectively. Excretion of total sterol increased (P < 0.05) with increasing βCD supplementation and the composition of excreted bile acid was significantly altered in pigs fed βCD. The cholesterol levels of pig backfat, belly, loin, and ham were reduced as βCD supplementation increased (P < 0.05) in the diet.
